## Description

## Overview

The LILYGO T-Connect is an industrial-grade communication development board built on the ESP32-S3-R8 chip with 16MB flash and 8MB PSRAM. It provides four independent communication interfaces: three RS485 serial ports and one CAN bus port, enabling mutual switching between modules for flexible data routing. Each RS485 and CAN interface has a tested range of 35 meters, making it suitable for factory floor automation, multi-sensor data acquisition, and integration with legacy industrial equipment. The onboard APA102 LED indicates status at a glance. The ESP32-S3 also provides 2.4GHz WiFi and Bluetooth 5 LE connectivity for wireless data relay and remote monitoring, making the T-Connect a capable bridge between wired industrial protocols and modern IoT cloud platforms.
